- This in nt onr lat c rt n el i p o emen s inbuild g n s, a d a f r itsprincipal object the provision of'an improved construction of this character which will be 5 hig ly jflici t i s a econ mic n m n ufacture. The salient object of this inventionis the Pr v sion of a imp e n t o bu l ing construction embodying dead air chambers 19 which provide'an improved insulation against heat-and cold. i r I Another object of the invention is the provision of animproved unit for building construction whichmay be quickly and economi 15 ca'lly assembled with za minimum of labor,

A further object of the invention is the provision of an improved building unit pro-- vidinga substitute for brick and the like which provides a surface to which plaster or 29 the like may be applied directly without the use of lat-hs or the like. v

()ther objects will appear hereinafter.

' The invention consists in the novel combination and arrangement of parts-to be hereinafter described and claimed. 1

The invention will be best understoodi'by reference to the. accompanying drawing, showlng the 'preferred' -form of construction and in which Fig. -1 is atop plan view of a typical ing wall section showing a preferred formof construction for our invention and depicting the invention in assembledpositiony Fig. 2 is a sectional view taken substantially on the line 2'2'in Fig. 1; v i Fig. 3 is a sectional view taken substantially on the line 3-3' in Fig.1; 1 p i Fig.4 is a perspectiveview of one unit of the invention showing a preferred construcs tion of the plaster receiving surface; s

As shown 1 i inclusifve, V :7 the section 10 comprises'oppositely extending 2 y be seen thjat thetongue 17 is narrower than the recess 17 so thatin assembling the inven tion the. tongue 16 ofone section is inserted into the recess 17 of the next'adjacent unit and space is'provided for -th e insertion of asuitable-bindi-ng agent such as mortar 18 or the like therebetween. a r

In the form of construction of our'i-nvention depicted in Figs. 1 to 4 eachbuilding unit comprises the section 10'and a substan ia ly' lar. ti 9 Whi h' i ii n d t the section lOby means of straps 20 which include offset, portions 21. The straps 20 may be made of any suitable material such,

rigidly and permanently secured in position in the sections 10 and 1;9during themanu-v facture thereof. 1, While two strapsj20. are p c ed be we n ach pa r o -s c i n l a 19 it is manifest that thisnumber may be a iedth ut d p r g om h purview of our invention. Thesection 1-9 comprises sidewall porw-hich definea dead air chamber 26, which is preferably somewhat wider than the air chamber Provided in" each section 19 is a tongue portion 27, similar to the tongue portion 1 6, and a recess 28 similar to the recess '17 Bylreferring to Fig; 1 it may be seen that iniassembling our improved unit the tongue 27 of one section 19 is inserted in the groove 28 of the next adjacent section 1 9 and secured in position by means of mortar 18forthe like-i; W1 1 1 v A winz Fig '2 here is provided i each of the straps 20 a plurality ofopenings' '29 and the manufacture ,of ourimproved bu ld ng first itm y se n tha the refracfor example, as steel and these straps are 7 tions 22 and 23 and end portions 24 and 2 5 formed between the sections 10 and 19 when Vented. As shown in Figfl', the offset'pon" tions 21 of the straps 20 are preferablysubstantially- U-shaped and have the bight portions thereof directedinwardlyawith a por.

tion of the bight portion of each strap extended acrossan air chamber 30 which is our improved unit is assembled in a w'all such as shown in Fig. 1. e

Providedrin the outer surface of the wall 23 of the section l9 isa network of intersecting grooves comprising vertically ex tending grooves 31 and longitudinally extending grooves 32 whichprovide a retaining surface for plaster or the like.

In Fig. 5 amodified form of construction is depicted and'in-this instance the sections 10 and 19 have provided therebetween a middle section 33, thereby defining air chambers 34 and 35. In this form of construction straps 36 are provided which are substantially. similar to the straps 20 but include 'longer offset portions 37; which project through the section 33. V Depicted in Fig. 6 is one form of orna mental surface'gthat may be formed in the surface of the'outer wall 11 of the section 10 though. it is understood that any desired form ofornamental surfacing may be formed on the surface of the outer wall. From the foregoing description of our invention it is manifest that we have provided an improved building unit which embodies dead air chambers providing a highly efficient wall insulation against heat and cold. It is likewise apparent that while being durable, economical and simple in construction our improved unit permits of rapid assembly in building thereby effecting a material economy in labor. r While we have illustrated and described the preferred form of construction for carrying our invention into eflect, this is capable of variation and modification, without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appendedclaims. 7

Having thus described our invention what we claim as new and desire to protect by Let ters Patent is: j

1. A building unit-comprising spacedapart sections defining an air. chamber therebestrap members including an offset portion extended across said first-named air chamberand having its endsembedded in said sections, and the portions of said strap members atoppo'site sides of'said oifset portions hav-, ing perforations therein through which the material composing the said sections l'is adapted to extend.

2. A' building unit comprising spaced apart outer sections, a middle section dis posed between and spaced apartgfromsaid outer sections defining a plurality of air chambers therebetween, each of said outer sections havlng an air chamber defined interlorly thereof, said outer sections including end portions, a tongue in one end portion of each of said outer sections, each of said outer sections having a groove formed therein in the end portion thereof opposite said tongue, the tongue of one outer section being adapted in assembled position to be fitted into the groove of the next adjacentcorrespond ing section, and means for securing said outer sections and said middle section in spaced relation to define said first-namedair chambers, said means including strap Inembers provided with offset portions extendedacross said first-named air chambers and through said middle section; 4 *3. A building unit comprising spaced apart outer sections each having an intra-' wall air chamber defined therein, a middle section disposed between andspaced' from said outer sections to provide therewith'a plurality of interwall air chambers, and strap members each including an offset portion 'exan interwall air chamber, and means for con} necting said sections together in spaced relationship to provide said interwall chamher, said means comprising a member including an offset portion extended across said interwall chamber and having its ends embedded in said sections at the ends of said intrawall chambers, the embedded portions of said member having apertures therein through which the material composing said sections is bonded. 5 In testimony whereof we affix our signa-- tures.
